LoLA compared to other tools («Known» models, StableMarking)
Last Updated
Jun 28, 2021

Introduction

This page presents how LoLA do cope efficiently with the StableMarking examination face to the other participating tools. In this page, we consider «Known» models.

The next sections will show chart comparing performances in terms of both memory and execution time.The x-axis corresponds to the challenging tool where the y-axes represents LoLA' performances. Thus, points below the diagonal of a chart denote comparisons favorables to the tool while others corresponds to situations where the challenging tool performs better.

You might also find plots out of the range that denote the case were at least one tool could not answer appropriately (error, time-out, could not compute or did not competed).

LoLA versus GreatSPN

Some statistics are displayed below, based on 2458 runs (1229 for LoLA and 1229 for GreatSPN, so there are 1229 plots on each of the two charts). Each execution was allowed 30 minutes and 16 GByte of memory. Then performance charts comparing LoLA to GreatSPN are shown (you may click on one graph to enlarge it).

Statistics on the executions
  LoLA GreatSPN Both tools   LoLA GreatSPN
All computed OK 370 46 663   Smallest Memory Footprint
LoLA = GreatSPN 0 Times tool wins 924 155
LoLA > GreatSPN 0   Shortest Execution Time
LoLA < GreatSPN 0 Times tool wins 995 84
Do not compete 0 0 0
Error detected 12 0 0  
Cannot Compute + Time-out 37 373 147


On the chart below, denote cases where the two tools did computed all results without error, denote cases where the two tool did computed the same number of values (but not al values in the examination), denote cases where LoLA computed more values than GreatSPN, denote cases where LoLA computed less values than GreatSPN, denote the cases where at least one tool did not competed, denote the cases where at least one tool computed a bad value and denote the cases where at least one tool stated it could not compute a result or timed-out.

LoLA wins when points are below the diagonal, GreatSPN wins when points are above the diagonal.

LoLA versus ITS-Tools

Some statistics are displayed below, based on 2458 runs (1229 for LoLA and 1229 for ITS-Tools, so there are 1229 plots on each of the two charts). Each execution was allowed 30 minutes and 16 GByte of memory. Then performance charts comparing LoLA to ITS-Tools are shown (you may click on one graph to enlarge it).

Statistics on the executions

LoLA < ITS-Tools 0 Times tool wins 929 256
Do not compete 0 0 0
Error detected 12 0 0  
Cannot Compute + Time-out 140 5 44


On the chart below, denote cases where the two tools did computed all results without error, denote cases where the two tool did computed the same number of values (but not al values in the examination), denote cases where LoLA computed more values than ITS-Tools, denote cases where LoLA computed less values than ITS-Tools, denote the cases where at least one tool did not competed, denote the cases where at least one tool computed a bad value and denote the cases where at least one tool stated it could not compute a result or timed-out.

LoLA wins when points are below the diagonal, ITS-Tools wins when points are above the diagonal.

LoLA versus Tapaal

Some statistics are displayed below, based on 2458 runs (1229 for LoLA and 1229 for Tapaal, so there are 1229 plots on each of the two charts). Each execution was allowed 30 minutes and 16 GByte of memory. Then performance charts comparing LoLA to Tapaal are shown (you may click on one graph to enlarge it).

Statistics on the executions
  LoLA Tapaal Both tools   LoLA Tapaal
All computed OK 146 77 887   Smallest Memory Footprint
LoLA = Tapaal 0 Times tool wins 664 446
LoLA > Tapaal 0   Shortest Execution Time
LoLA < Tapaal 0 Times tool wins 919 191
Do not compete 0 0 0
Error detected 12 0 0  
Cannot Compute + Time-out 68 149 116


On the chart below, denote cases where the two tools did computed all results without error, denote cases where the two tool did computed the same number of values (but not al values in the examination), denote cases where LoLA computed more values than Tapaal, denote cases where LoLA computed less values than Tapaal, denote the cases where at least one tool did not competed, denote the cases where at least one tool computed a bad value and denote the cases where at least one tool stated it could not compute a result or timed-out.

LoLA wins when points are below the diagonal, Tapaal wins when points are above the diagonal.

LoLA versus 2020-gold

Some statistics are displayed below, based on 2458 runs (1229 for LoLA and 1229 for 2020-gold, so there are 1229 plots on each of the two charts). Each execution was allowed 30 minutes and 16 GByte of memory. Then performance charts comparing LoLA to 2020-gold are shown (you may click on one graph to enlarge it).

Statistics on the executions
  LoLA 2020-gold Both tools   LoLA 2020-gold

LoLA versus BVT-2021

Some statistics are displayed below, based on 2458 runs (1229 for LoLA and 1229 for BVT-2021, so there are 1229 plots on each of the two charts). Each execution was allowed 30 minutes and 16 GByte of memory. Then performance charts comparing LoLA to BVT-2021 are shown (you may click on one graph to enlarge it).

Important: here, LoLA is compared to BVT-2021. It is a good way to check how LoLA compete in terms of resource consomption with the best tools (even virtual). When LoLA is best, the corresponding plots are on the diagonal of the scatter plots chart.

Statistics on the executions
